Thanks for the heads up....bolt and slide spring were part of the caliper "kits" as were new copper gaskets for the brake line interface. All of the parts were in good shape (except the rotor and pads), and everything that slides received a coating of a special brake parts lube - similar to never-sieze, but made specifically for brake slide/contact areas.

Picture #1 below shows the new master cylinder in place - also purchased a "vacuum kit" to bleed the master cylinder, lines, and calipers - 40 bucks very well spent. Besides the master cylinder, also note the support from the MC bolts to the frame - this has to come off as outlined earlier. One of the new brake hoses is visible at the lower left hand corner.

Picture #2 shows part of the "while your at it" scope of work expansion....ran cold compression numbers while I had every thing apart......not too bad considering 80,000 miles, lugging around 8 tons, and turning over 3,000 rpm at 60 mph.....150 to 170 psi. The plugs (platinum points) had about 8,000 miles on them, and really needed to be replaced. The electrodes were very rounded and had lost a lot of metal.....went back with conventional plugs. The driver sides were very clean - no carbonizing at all, but the curb side (#4 and #6) had a bit of carbon/buildup - but not bad.....when the plugs were changed last the #8 cylinder evidenced by far the worst buildup, but it also had a burnt plug wire....#8 looked pretty good this time.

Hard to believe that it's mid September and the temp index is well over a hundred degrees - the good thing about the MoHo being down right now is that it is still too hot to go camping....a very welcome benefit of the metal roof over the parking area is that a couple of well placed fans on the concrete makes it almost bearable when working under the unit.

The way you have done this brake job is the ONLY WAY. Like me WHILE YA GOT IT APART replace everything. Then ya know what ya got.
I have done brake jobs on big trucks that I owned in my day and I know its not all fun an games.
GOOD JOB now You can sit back and enjoy the fruits of your labor.

Bump to keep this up front. Would recommend a sticky thread that contains links to great maintenance write-ups like this. Some times these threads get buried deep into the archives.
